Oooh, style refinement.
My thoughts on Rainbow Dash:
She's a little brash and impulsive. I have nothing against the girl, she really is sweet and loyal, even though she keeps up an air of distance. Certainly I am fond of her, maybe not as much as some of the other mane six, but she's proved to be an asset to the team and to her friends despite her shallowness (and indeed anti-intellectualism) . I don't know why she's so popular, she really does seem to be the "figurehead" for bronies, and I'm thinking it's probably because of the blue colouring, and 'awesome' lightning bolt cutie mark. Despite not being my favourite she certainly is okay in my books.
Edit: changed it to purple, woo.
